Does Premiere Elements 14 support the custom NVidia GeForce GPU in the Microsoft Surface Book for editing, playback, rendering, and/or export?
Adobe's "Supported Device" list (Supported devices | Adobe Premiere Elements) has several GeForce cards, but nothing specific on the Surface Book.
I'm assuming that PrE14 can use the Intel HD graphics in the Surface Book and Surface Pro. Just looking whether the NVidia card in the Surface Book would be an advantage with PrE14.
Most likely the program will run just fine on that GPU. Though Premiere Elements really doesn't use much GPU power, so there is little advantage to an upgraded GPU card.
